ClusterNonOverlapEnforcement
Resolves the ambiguity when clusters overlap in a context of a
given property type (e.g.: material). This command is used
primarily by ApplyShader.
It either removes the overlap from the selected clusters, from the
existing clusters, or simply lets the overlap happen.
oReturn = ClusterNonOverlapEnforcement( InputObjs, Property, ActionWhenLocalMaterialsOverlap ); |
Returns an XSICollection containing the clusters found to be overlapping with the target cluster(s).
| Parameter | Type | Description |
|---|---|---|
| InputObjs | String | List of clusters (probably
selected) against which all clusters will be tested for
overlapping.
Default Value: Current selection |
| Property | String | Example of a property the existing clusters must have in order to be tested. |
| ActionWhenLocalMaterialsOverlap | siActionWhenLocalMaterialsOverlap | What to do with the clusters found to be overlapping with the
target cluster(s).
Default Value: siRemoveFromSelectedClusters |
